This volume compiles proceedings from an international symposium focused on active control within mechanical engineering. It presents research and technical developments in the dynamic control of mechanical systems, with particular emphasis on vibration suppression, suspension technologies, and intelligent control strategies applied to motor vehicles and industrial machinery. Contributions explore both theoretical frameworks and practical implementations, reflecting state-of-the-art methodologies in system dynamics and control engineering during the mid-1990s. The collection serves as a reference for researchers, engineers, and graduate students interested in advanced control applications in mechanical systems.
